PROBLEM TO BE SOLVED: To execute safely a test for grasping precisely heat transfer characteristics of an instrument resisting a pulsating high heat flux. SOLUTION: This device is so composed that a current is carried to a heating element 3, and that a heating transfer surface 4 is overheated by an electric power, and that heat transfer characteristic from the heating surface 4 is tested. In this case, an electric power for heating is accumulated in an accumulating device 10, and accumulated electric energy is sent instantly to the heating element 3, and pulsating heating transfer characteristics are grasped. And, this device has a charge/discharge device for charging the accumulating device 10 every time before one test, and for allowing the device 10 to discharge every time after finish of the test.
